Air cooled heat exchangers | Air cooled condensers

Air Cooled Heat Exchangers are used mainly in refineries in oil processing and in the processing and transportation of natural gas where the worldwide accepted API (American Petroleum Institute) standard intended for the special requirements of such demanding operations was developed many years ago, according to which almost all clients order such air-cooled heat exchangers. In technical jargon, these heat exchangers are indicated as API-exchangers. They are distinguished by their use at high operating temperatures and pressures, with highly corrosive and flammable media requiring special structures, materials and demanding welding procedures (plug chambers with extraordinary sheet metal thicknesses, duplex steels, etc.). In other industries, the conditions are not so demanding and the technical design of heat exchangers is resolved according to traditions in such industries, according to the specific requirements of customers or our experience, naturally considering the applicable standards for the construction of such pressure facilities.

Electricity production processes result in emissions of low-potential heat into the atmosphere. Air-cooled Condensers (Heat Exchangers) use corrosion-free media at low pressures (water steam, water and glycol mixtures). In many cases cooling of extreme thermal powers is needed. This includes cooling of gas and diesel engines, gas and steam turbines and condensation of the emission steam of steam turbines. More and more, air-cooling replaces water-cooling in power engineering, where it is used a standard as water is rarer in some industrial areas and more expensive. In many areas which require the production of electricity, water sources are lacking and in concentrated industrial areas where water is available, its price is very high.
